APPARATUS FOR PRODUCING SUCCESSlVELY-CHANGING PICTURES 0RADVERTISEMENTS.

SPECIFICATION forming part of Letters Patent No. 617,244, dated January3, 1899.

Application filed August 6, 1897. Rerial No. 647,346. (No model-l T0rtZl whom it may concern.-

Be it known that I, CHARLES FOUGERAT, painter, of Lyons, in the Republicof France, have invented certain new and useful Improvements inApparatus for Producing Successively-Ohanging Pictures orAdvertisements, (patented in Great Britain November 6, 1897, No. 402 5)and I do hereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to apparatus for producing successively-changingpictures,drawings, advertisements, or the like, and has for its objectto provide means whereby the exhibits may be changed from one to anotherin an extremely short interval of time, a peculiar bizarre effect beingproduced at each change.

To this end the apparatus consists of a plurality of sustaining devicesof suitable form and construction appropriately mounted in a frame toform a screen. A band or hands of any suitable flexible material, suchas canvas or the like, and carrying a plurality of pictures or otherexhibits divided into sections is passed over the sustaining devices,the sections of the pictures being so disposed upon the flexiblematerial that component parts of a complete picture will be displayed atthe same time upon their respective sustaining devices, means beingprovided for operating the flexible material to simultane-' ously movethe component sections of the different pictures into and out ofposition upon the sustaining devices.

The invention further consists in the details of constructionhereinafter described and claimed.

In the accompanying drawing the figure is a diagrammatic sectionalelevation of my improved apparatus.

Referring to the drawing, L represents the sustaining devices in theform of laths or boards of any suitable material, which compose ascreen. These sustaining devices are appropriately mounted in aframe(not shown) at a distance apart sufficient to admit of two adjacentbands of the flexible material passing freely between them. In thisinstance a series of bands are provided, one for each sustaining device.The first band is wound upon a roller R and unwound from a roller S, or

vice versa, while the second and third bands are unwound from rollers Sand S onto a seccond winding-roller R, or vice versa, and so 'on withall the bands, at Winding-roller being provided for every two bands.According to the height of the changing picture or advertisement to beshown a corresponding number of sustaining devices, and consequentlyalso of bands, with their operating and winding devices similar to thosejust mentioned, may be employed. On each of these hands a componentsection of each of the pictures to be displayed is applied by paintingor otherwise, so that each of the bands must be brought into operationto produce a complete picture or exhibit, and as each section of a bandcorresponding to the width of its sustaining device is painted orotherwise provided with part of a different exhibit to yield successiveand complete pictures or exhibits by the combined simultaneouspresentation of corresponding sections of all the bands it is obviousthat an intermittent forward or backward rotation of the rollers toanextent sufficient to displace the canvas a Width corresponding to thewidth of a sustaining device will change the exhibit, it being possibleto cause the whole of the exhibits to appear in succession.

The different rollers S S are provided with any suitable means forstretching the bands, such as weights 1),

On the shaft or journal of each roller R is keyed a worm-wheel r. Ashaft X, carrying a series of endless screws V, is mounted vertically toengage all the worm-wheels r with said endless screws. By operating theshaft X mechanically or otherwise an equal rotary movement may beimparted to all the rollerssimultaneously. All the bands will thus besimultaneously displaced on the sustaining devices L in the directionsindicated by the two sets of arrows in the drawing, thus producing atfirst a novel, original, and interesting optical illusion during thechange of the exhibit by the-blurring of the pictorial or other sectionsuntil the latter have moved sulliciently toproduce another completepicture or exhibit.

The rotary motion of the rollers, which is shown as produced by endlessscrews, may of course be obtained by any other suitable mechanismsuch,for instance, as beveled gearing. There may be joined with thedriving-gear of the rollers a regulator or register for always givingexactly the same displacement to all the bands in order that the fittingtogether of the different sections of the pictures or exhibits mayalways be perfect.

An ordinary commutator or other reversing device may be combined withthe apparatus to enable the bands to be immediately and automaticallyreturned as soon as they have presented their final exhibit by reversingthe direction of rotation of the rollers. These inverse successivedisplacements of the bands forward and backward are each represented inthe accompanying drawing by different arrows.

Attention is especially drawn to the fact that in my apparatus thecomponent sections present an apparently unbroken surface, this beingtrue even during the change of the exhibits, which constitutes anespecially novel feature of the apparatus, as during the change of anexhibit the picture is blurred and produces by the mixture of colors abizarre etfect,which by constantly varying constitutes one of the chiefattractions of the apparatus. It may also be pointed out that by theemployment of my apparatus itis possible to display a very large numberof exhibits in a comparatively small space. It is to be understood thatthe width of the sections of the pictures may be varied as desired tosuit the nature and dimensions of the changing pictures, advertisements,or the like which are to be shown.

Having thus described my invention, what I claim is- 1. In apparatus forproducing successivelychanging pictures, designs, inscriptions or otherexhibits, the combination of a plurality of laths L arranged in a singleplane to form a screen, with small intervals between each lath, acorresponding number of flexible bands arranged one over each of saidlaths and bearing each a different section of each exhibit, a series ofwinding and tension rollers for said bands, a series of worm-wheels rkeyed on the shafts or journals of said winding-rollers, and a singledriving-shaft X carrying a series of endless screws V to engage saidworm-wheels to impart an equal movement to all the winding-rollerssimultaneously, substantially as hereinbefore described.

2. In an apparatus for producing successively-changing pictures or thelike, the combination with a plurality of laths arranged in a singleplane to form a screen of a corresponding number of flexible bandspassed one over each of said laths, said bands carrying componentsections of the various exhibits, a plurality of winding-rollers formoving said flexible bands and a single driving-shaft and means fortransmitting from said shaft an equal movement simultaneously to all thewinding-rollers to display conjointly the various sections of anexhibit, substantially as described.

3. Inapparatusforproducingsuccessivelychanging pictures, designs,inscriptions, or other exhibits, in which a plurality of laths arearranged in a single plane to form a screen with a corresponding numberof flexible bands carrying sections of the exhibits passed one over eachof said laths, the combination with the flexible bands, of a pluralityof winding rollers R arranged one for every two adjacent bands, a seriesof tension-rollers S S arranged separately one for each of the remainingends of the bands, a single driving-shaft, and means for transmittingfrom said shaft an equal movement simultaneously to all thewinding-rollers,substantially as hereinbefore described.

4:. An apparatus for producing successively changing pictures, designs,inscriptions or other exhibits comprising the combination of a pluralityof laths L arranged in a single plane to form a screen with smallintervals between each lath, a corresponding number of flexible bandsarranged one over each of said laths and bearing each a differentsection of each exhibit, a plurality of windingrollers R arranged onefor every two adjacent bands, a series of tension-rollers S S arrangedseparately one for each of the remaining ends of the bands, a series ofworm-wheels r keyed on the shafts or journals of said winding-rollersand a single driving-shaft X carrying a series of endless screws V toengage said worm-wheels to impart an equal movement to all thewinding-rollers simultaneously, substantially as hereinbefore describedand shown.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES FOUGERAT.
